Integration between BPC 10 Nw and BI4

Hi experts,

i would know how is possible to integrate BI4 platform and BPC 10 NW.

I find that is possible to create an OLAP connection toward an BPC 10 Netweaver but which is the difference respect an OLAP connection toward an BW system?

I tried to use the OLAP connection toward BPC server but on analysis for OLAP is not possible to create analysis on "Real time Cube" where planning data is recorded.

Thank you.

Kind Regards.
